Detailed explanation-1: -The ATP yielded in aerobic respiration is about 38 molecules by complete oxidation of a single glucose molecule. On the other hand, anaerobic respiration produces only 2 ATP per glucose molecule. Thus, the most efficient form of respiration is aerobic respiration.

Detailed explanation-2: -With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.

Detailed explanation-3: -Aerobic respiration is much more efficient, and produces ATP much more quickly, than anaerobic respiration. This is because oxygen is an excellent electron acceptor for the chemical reactions involved in generating ATP.

Detailed explanation-4: -Aerobic respiration is 19 times more effective at releasing energy than anaerobic respiration because aerobic processes extract most of the glucose molecules’ energy in the form of ATP, while anaerobic processes leave most of the ATP-generating sources in the waste products.

Detailed explanation-5: -Anaerobic respiration is a process in which energy is released from glucose without requiring oxygen. It takes place in the cytoplasm. It coverts glucose into ethanol and carbon dioxide. It is less efficient than aerobic respiration as it releases less energy than the energy released in aerobic respiration.
